Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610544, here are decompositions:

5 + 31610539 = 31610544
23 + 31610521 = 31610544
41 + 31610503 = 31610544
107 + 31610437 = 31610544
131 + 31610413 = 31610544
151 + 31610393 = 31610544
181 + 31610363 = 31610544
191 + 31610353 = 31610544

Showing the first eight; more decompositions exist.
